The much-awaited Agartala-Anand Vihar Rajdhani Express was flagged off from here today by Minister of State for Railways Rajen Gohain. The train would formally start its operations from November 6. The Rajdhani would leave the Agartala station for Delhi on Mondays and embark on its return journey from Anand Vihar on Wednesdays. The 2457-km-long journey would be covered in 40 hours and 50 minutes, a Northeast Frontier Railway (NFR) official said. Flagging off the train, Gohain said the Centre had plans to extend Rajdhani services to Imphal by 2020.
